Abstract: 

Objective: To assess the correlation between blood profile and reproductive disorders in dairy cattle.
Design: Field study.
Animals: Seventy two healthy and 72 affected Holestien cows.
Procedure: Recording the data of reproductive failures of cows between 2 to 5 calving no. Palpation of uterus and ovaries per rectum were carried out to assess the reproduction system failure. Blood samples from jugular vein to determine metabolic profile.
Statistical analysis: ANOVA followed by Duncan’s test.
Results: Results showed that blood urea in the repeat breeder cows were significantly higher than healthy cows (P<0.05). However, concentration of blood glucose in the healthy cows, persistent corpus luteum cows and repeats breeders were the same but, it decreased in inactive ovaries and persistent follicle cows (P<0.05). The phosphorus concentration in healthy cows was higher than static ovaries, persistent follicle and repeat breeders cows (P<0.05). The blood calcium concentration was constant in all groups. The amount of Progestrone of repeat breeders was lower than the healthycows (p<0.01).
Conclusion: These data suggested that it is possible to diagnose reproductive failures in dairy cows by using metabolic profile test to improve pregnancy rates in dairy cttle herds.
